WATER LINE PIPE BURSTING
According to the EPA major expenditures will be needed to replace water transmission and distribution lines over the next twenty years. A recent EPA study stated that water systems throughout the country are in a state of massive deterioration and could bring forth many health issues.
Line failures are due to the following reasons:
• Under sizing of current lines
• Tuberculation build up of existing lines
• Joint failures in existing lines resulting in Inflow and Infiltration I/I
PIPE BURSTING FOR WATER LINE REPLACEMENT
When designing water line replacement projects, pipe bursting should be considered first due to the social impact of the dig and replace method of construction and its ability to upsize a line. During the pipe bursting process a bursting unit splits and/or fractures the existing pipe while simultaneously installing a new pipe of the same or larger size into the annulus created by the unit’s forward movement.
When going to a bigger size pipe, things such as soil conditions, original trench width, clearance and surrounding utilities need to be considered. Pipe bursting for water applications can be accomplished with several types of new pipe, however, over 95% of all water pipe installed by the pipe bursting method has utilized High Density Polyethylene Pipe (HDPE). HDPE pipe is a tough, durable and yet inexpensive pipe. HDPE pipe is now also guaranteed for over 100 years of service life! For more information, please refer to PUCC’s Contact Page
• Replace pipe ranging in size from 4 to 54 inches
• Can be used to replace pipe for the same size and to replace pipe by up sizing.
• Only trenchless pipe rehab method that can actually upsize the existing pipe.
BURSTING EFFECTIVE FOR:
• Clay or VCP pipe
• Concrete or RCP pipe
• Asbestos cement or AC pipe
• Plastic pipe
• Ductile iron pipe DIP
• Steel pipe or cast iron pipe
STATIC BURSTING METHOD
Water line pipe bursting is accomplished by the Static Pipe Bursting method. The static pipe bursting consists of five simple steps:
(1) Dig insertion and exit pits at the beginning and the end of line segment. One to place the bursting machine and the other to use as a pipe entrance pit.
(2) Shuttle your static rods from starting point to the end point in the line.
(3) Attach the expander and pipe to the static rods
(4) Pull the rods, expander and pipe back toward the bursting machine.
(5) Reconnect the services

LATERAL LINE BURSTING
The recent inflow and infiltration (I&I) reduction programs from the EPA have focused mostly on the repair and replacement of sewer and water mains. These programs like CMOM (Capacity Management Operation and Maintenance) have mandated several municipalities to reduce sanitary sewer overflows (SSO) and combined sewer overflows (CSO). The answer for many municipalities has been to line the failing sewer or water mains or to pipe burst the existing sewer and water mains. However, little attention had been focused on the problems with leaking and failing laterals (service lines to the homes or business).
The EPA has now determined that failing lateral service lines are responsible for much of the total I&I that is occurring in the sewer and water system. The solution for fixing I&I problems on the mains is not always the same solution to fixing the laterals. Often there is not enough capacity in the existing laterals to justify relining. Also, the laterals or service lines are often located underneath well-landscaped yards, an entryway, a shipping or receiving bay, a sidewalk or other obstacles. These factors play a big role in why pipe bursting for service laterals is continuing to grow at a rapid pace.
LATERAL PIPE BURSTING SOLUTION
Pipe bursting service laterals can significantly help reduce I&I and with the upsizing capabilities of the method, it is often a best solution for lateral I&I problems. PUCC has recently replaced several lateral services through bursting in Jacksonville, Fl. The method is fast, inexpensive (compared to dig and replace methods) and very valuable socially to the homeowners and business owners that were affected.
Lateral Pipe Bursting is accomplished with some very easy and quick steps:
First, a pit is dug near the home to place our lateral bursting rig
Second, a pit near the main line is dug
Third, the main is disconnected from the service line
Fourth, the bursting head is inserted into the existing line with the new HDPE attached
Fifth, the new line is pulled through the existing line and the service lateral is connected to the main.
PUCC continues to utilize pipe bursting for laterals as often as possible. Lateral pipe bursting is a very cost effective and important method for overall I/I reduction.
SEWER SERVICE CONNECTIONS WHEN PIPE BURSTING SEWER LINES
Studies have shown that services account for roughly half of Inflow/Infiltration problems. Water tables in trenches are raised when problems associated with the main are corrected. So, if the service reconnects are not watertight, return on investment spent on correcting the main is diminished. Therefore, whenever possible hard reconnections at services are advisable when addressing Inflow/Infiltration problems. Most agree that a hard reconnect is the most cost effective method to solve Inflow/Infiltration problems.
Because service connections are fragmented along with the main during the pipe burst process, services associated with pipe bursting must be reconnected with a hard reconnect at the main.
